Specification of Letters Patent.

' Application filed December 19, 1908. Serial No. 468,874.

' To all whom it may concern:

Be it known that I, THOMAS F. SooTT, a citizen of the United States, residin at the city of Everett,.in the county of Middlesex 5 and State of Massachusetts, have invented new and useful Improvements in Vehicle- Whecls, of which'the following is a specification. p

This vention relates to a wheel for an e, or other vehicle, having a hub in secti us or arts severally arranged side by side and wit the outer sections journaled on a common axle, and the middle or intermediate section free to turn about the axle and to slide between said outer sections in a vertical direction across said axle, and a pair of resilient cushions, preferably pneumatic rings of india rubber, or other suitable material, which are arranged one at each side of the middle section and about the outer section thereat, and are confined to said several sections all so as to turn as one; the middle section being suitably adapted, as for illustration, with radially extending spokes and a tire, as well known, to serve with a hub, such as aforesaid, as a wheel resiliently cushioned as aforesaid.

The invention mainly consists in the combination with a wheel, substantially such as of keys joining the outer sections to the middle section, and in a manner to turn in common with said several sections and to permit the-aforesaid slide of the middle section, and of a horizontal latsubstantially as hereinafter described. Further the invention consistsof improvements in detail, as will hereinafter appear.

In the accompan ing drawings," forming cation, a vehicle-wheel embodying this invention is illustrated in the most approved form of construction and arrangement of its several parts.

Figure 1 is a side elevation of the hub and central portion only of the wheel and axleand the axle, at each end, broken off. Fig. 2 is a central transverse vertical section 'of the hub and central portion of the wheel-hub shown in Fig. 1, and in'the vertical longitudinal plane of the axis of the wheel-axle which is m side elevation, and at each end broken ofi'.

Fig. 3 is a face view of a ke detached.

In the drawings, A and l are the outer sections and C is the middle section of the to all said sections; E, E are diametrically opposite spokes and F is the tire of said middle hub-section, or in other words of the wheel proper.

The outer hub-sections A, B, are at each side of the middle or intermediate hubsection C, and both said hub-sections A, B, are journaled on the axle D and they are held on a common bushing-sleeve G, which extends between the two and makes the bearing proper thereof on the axle. The middle hub-section C is between the two outer hubsections A, B, and it has a central bore H of lar er diameter than that of the bushing G, an otherwise it is arranged so that it can slide vertically between said outer sections and in a direction acrossthe axle,

J J ah'e the pair of resilient cushions, particularly shown as pneumatic rings of india rubber, or other suitable material. There is a cushion J about each outer hub-section A, B, and, in each instance, each is seated in the concave circular edge K of the section and otherwise it is located and confined in Patented Nov. 2, 1909. I

its said bearing between said section and the circular running concave face about the periphery at the inner side of a circular runof the middle hub-section C. The middle hub-section diametrically divided into two similar parts secured together by headed screw-bolts'N and nuts 0 (two only shown) located at and about the extension M of the middle hub-section.

The outer hub-sections A, B are held on the axle D and against each side-face of the middle hub-section O, by means of screw nuts P, P, which are screwed onto the screwthreaded ends of the bushing G and enter into circular running recesses Q, Q of suitable diameter and depth in the outer hubseotions A, B, and I accidental turning by means of screw-pins R, R screwing into and through them and into the outer hub-sections A, B.

The face S of each outerside of the middle hub-section-C andthe face '1 of each inner side of each outer hub-section and which are adjacent to each other have 'a recess U and V, respectively therein, and said two recesses U, V, in each instance, are opposed to each other and contain in common a similar key W in, the form of a plate (Fig. 3) and each key W lies within Said opposed recesses and has a central circular opening or bore through it corresponding in dlameter to the central circular opening or C is centrally and" 11mg and lateral extension M at each side hub, and outside of said lateral also are fastened against bore H of the middle hub-section 0. Each recess U of the middle hub-section C is greater in its vertical dimension than the dimension of the key Win a wrrespondin direction, and so, as is lain, the middle hub- 7 section is free to move tween the side'hub- 10 1 than the dimension of the key W in a corresponding direction and so, as is plain, each' v movements stated.

sections A, B, and on the'key-plate W in a vertical direction across the axle. And again the recess V of each side hub-section A, B 'is greater in its horizontal direction side hub-section and the key-plate are free for amovem'ent in a horizontal direction.

across the axle, and otherwise than as explaine'cl the dimensions of said several re- It isnot intended to limit this invention in any respect. to the resilient cushions for the wheel described, .as it is obvious others may be substituted for them, and this invention in no manner consists therein, the same being well known in every respect and particular.

' Having thus described my invention what I claim and desire to secure byLetters Pat- 7 ent is,

sections or parts arranged alongside of each other about and free to turn on a common axle, and the middle section free to slide between the outer or side hub-sections in a direction across the axle, and of twin resilient cushions at each outer section and confined therebetween and lateral extensions at the sides of the middle hub-section, in combination with keys about the axle and between the middle hub-section and each side hubsection and seated in recesses thereof which are adapted to allow of movements of the hub-sections in directions at right angles to each other and relative to the axle, substantially as described.

A vehicle-wheel, composed of a hub in sections or parts arranged alongside ofeach 1 other about and free to turn on a common axle, and the middle section free to slide between the outer or sidehub-sections in a di-' rection across the axle and of twin resilient cushions at each outer or side hub-section .and confined therebetween and lateral extensions at the sides of'the middle hub-section, in combination with a bushin to the axle, and screw-nuts screwed onto t outer ends of said bushing, and screw-pins fasmy hand in the presence of two subscribing.
